| Charter Mail SMTP & Blocked Port 25
We have just changed our internet service provider at one of our firehouses to AT&T from Charter. Now, several of our personnel cannot send mail over their Charter accounts (on Port 25) since port 25 is blocked outgoing by AT&T.
Does Charter have an alternative port to send mail with? |

Try port 587 i think that is the alternate port . Hmm Lazlow  i find that hard to believe i can send mail from a sbcglobal worldnet.att.net and a private domain from a charter account. It should work the other way as well. |

Just use the local ISP's SMTP server to send the mail for the accounts you are accessing from outside the Charter network. The incoming pop3 server will work fine.
You don't need to use the webmail applet.
I've been doing this for years. |

1) We're not real big on handing out the login information publicly to 60+ employees.
2) AT&T now requires that addresses that are being indicated as the "From" address must now be previously validated before AT&T SMTP servers will send the email.
At least AT&T, hell even my webhosting servers have a secondary port that is secure. You'd think that Charter would get with the program. If anyone knows of a way to implement this I'd be interested.
I may tell them they're SOL unless they want to use the webmail.

Port 587 does not work on Charter's servers. You can send email through a Charter account with a different "From" header. You can send email with your normal non-Charter SMTP server if a)you are on a CBN account without a port 25 block OR b) you are using a port other than TCP 25 to send mail (like AT&T does). You can send email over AT&T/Yahoo SMTP servers with a charter.net "From" header IF you have validated that charter address previously.

North Richland Hills, TX | Ok you might be right but a google search shows people have used that port on charter and that port is In the RFC table as reserved ports for email. |

Back when AT&T was SBC, they would remove the port 25 filter on your account if you asked them to. I think they even had an on-line form to submit the un-block request at one point. I haven't dealt with SBC/AT&T in a few years so I'm not sure what they do now, but you might want to call them and ask about it. |

I may just set up a sub account for personnel to send mail with. Or they can just use the webmail.
In the meantime, it sure would be nice if Charter had a SSL SMTP server running.

Haven't checked the IMAP on any Charter account for a while, but it was active at one point a few years ago and than was deactivated again and has been deactivated for a while now.
So you're saying that IMAP access to your Charter account is working now? |

Static accounts have no ports blocked by default.
the page referenced to lifts the block on dynamic accounts or you can just call in and have it removed and you have to do this for each Id that connects to PPPoE login servers. IE Subaccount if you use it to connect to dsl.
other wise you wont be able to send on port 25 with other domains unless you login to att servers and send it that way. |

This must be 'at&t Yahoo! HSI' service, then? Only the Yahoo! message submission servers have that requirement. Use 'smtpauth.sbcglobal.net' instead. Full email address is required for the login name.
Unfortunately, if you aren't big about handing out mail server login information, you may just be out of luck? AT&T just changed my legacy server to SMTP AUTH. There are few SMTP message submission servers left in the system which don't require login for access. Thanks, mostly, to AT&T providing wireless access to Express, Pro, and Elite accounts. Access servers from wireless hotspots means having an IP address which is not in the server ACL database as an authorized AT&T IP connection. So, instead of using IP addresses for determining who is authorized (as Charter SMTP message submission servers do), AT&T is changing to requiring login access from their users.
If this isn't "at&t Yahoo! HSI", please say: There are two other DSL services offered by AT&T.

However, does Charter use SMTP AUTH for access from outside of the Charter IP network? If not, then they probably employ an ACL of Charter IP addresses, and deny access to their SMTP message submission servers from outside of the Charter IP network. Unblocking outbound port 25 access will not address that problem.

Bingo(ACL). I just did not have the right terminology to explain it earlier. |
